Game dropping very hard in fps when any UI is open

My game is dropping from about 160 fps while just normally in the game to probably like <5 fps when having any UI open. This includes containers, inventory or the menu. This is only the case with shaders active, without shaders I dont get any fps drops. Installed mods are iris 1.9.6 and sodium 0.7.2 with fabric 0.18.0...

Iris Shader error

The message I received when trying to use a low-end shader essentially says "Pass sizes must match for drawbuffers [4, 6] Original width: 1920 New width: 1279 Original height: 1009 New height: 672". Shader I attempted to run: Butter_v1.2b.zip (curseforge). I need help with this, I don't want to sacrifice my 2015 computer...

Entities not rendering properly with SEUS HRR 3

This has been an issue all this time. Entities render with motion blur with SEUS HRR shaders - even vanilla ones. This was not the case in Optifine. I've tried IterationRT and the issue doesn't seem to be present there.

Stock shader freezes upon entering nether with distant horizons installed.

dh_terrain.fsh: dh_terrain.fsh: 0(380) : error C1503: undefined variable "dhProjection" 0(381) : error C1503: undefined variable "dhProjectionInverse" - I can occasionally get that error going back and forth a bunch, but it's not really consistent. It'll keep me frozen on the last frame, even if I fly around or whatever. Hud elements work fine, as does enabling any sort of shader....
Solution:
was caused by a DH config issue on the server side

Extreme Frame drop from 750 to 45fps

I’m currently playing on Minecraft 1.21.8 using the Modrinth Launcher with Iris + Sodium. I’m experiencing a big performance drop compared to last year, and I’d really appreciate some help identifying what’s causing it. A year ago, I could run BSL shaders at around 200 FPS consistently. Now, I only get 45–60 FPS, even though VSync is disabled. Render distance: 12 chunks → ~45 FPS with shaders Render distance: 2 chunks → ~60 FPS...

Potential lack of support for Vanilla Core Shaders?

Wynncraft released a new update in August 2025 called "Wardrobe Wonders", which featured some changes in gameplay, but most notably featured a massive graphical overhaul as well as new player customization features, namely the "glint" feature, which allows you to color your armor to whichever color you managed to unlock via their Silverbull Subscription service. I'm making this post to let it be known that allegedly the developers of Wynncraft have managed to utilize a feature introduced in the "Vanilla Core Shader" to recolor your armor pieces, that Iris, or any shader for that matter, doesn't seem to distinctly support. The end result is that colored cosmetics proceed to look green. This also applies to any player that recolors their armor AND their weapon should they choose to recolor it. I wouldn't mind if any developers related to Iris or their own shaders have a word with Wynncraft's developers to look more into this if this hasn't been looked at yet. This conflict severely bothers me as I'm able to run shaders and Wynncraft, but with colored cosmetics making myself and other players look green, it makes me less likely to either engage with cosmetic customizations (that I had to pay for btw), or the amazing shaders the community has released to the public....

Installing iris + fabric through iris .jar does not allow modding?

Hi there, i'm just going off of what i saw in the iris installation .jar. There is an option to install with fabric, which lead me to assume, that i will also get the option to add some other mods (e.g. ambient sounds). It appears adding mods to the mods folder in .minecraft does not do anything. Am i missing something?

game lags when i have crafting/inventory menu open

Whenever i open a crafting menu or my inventory while my shaders are enabled my frames go down to what looks like 5-10 fps to the eye, i don't have this problem when I'm not using shaders so its definitely something to do with the shaders, I'm on a pretty decent PC too and i average 400 fps with shaders on medium. when the lag occurs my frames don't go down while i have the F3 menu open and my ping doesn't go up either, like its some sort of visual bug that makes the game look like I've got terrible frames whenever my menu is open, as i said before this does not happen when i have shaders turned off and also doesn't just happen when i click on things in my inventory, even my mouse moves at what looks like 5 fps when in my menu i can see I'm having like 400-500 fps. I've looked through reddit forums and searched the internet for people who have the same problem as me but I've not been able to find a single solution....

Iris Installer Freezing when attempting to download

Hello, I am attempting to update to version 1.21.10 with Iris + Sodium but every time I try to run the installer it freezes and eventually closes itself without actually downloading. I have tried running Jarfix, verifying the download location, and trying multiple versions of Java and nothing is working. Any help would be greatly appreciated.
